ELECTRIC HAND LANTERN Filed March 2. 1931 @n HL 7? "5'3; @5070 Patented Jan. 3, 1933' UNITED STATES PATENT oFFicE j CARL H. LARSON, OF ELKHART, INDIANA, ASSIGNOIZR TO THE ADLAIIE COMPANY, LA. CORPORATION OF ILLINOIS ELECTRIC HAND LANTERN Application filed March 2, 1931. Serial No. 519,429.

This invention relates to electric hand lanterns and has for its object to produce a rugged, simple switch mechanism capable of withstanding the rigors of railway service.

75 Other objects of the invention will become apparent from the specification and appended drawing in which Fig. 1 is an elevation of the device; Fig. 2 is a vertical section through the low- ".10 er portion of the device;

Fig. 3 is a section through a lower portion of the lantern as indicated on the line 3-3 of Fig. 2;

Fig. 4; is a transverse section through the T5 lantern as indicated on the line H of Fig. 2.

The lantern, generally indicated by 10, comprises a casing 11 having a handle 12 preferably made of some insulating material. The lantern is supported by the base .20 and guard ring 13 to which it is attached by the legs 14 which are welded or otherwise suitably aflixed to a skirt 15 which telescopes for a short distance over the end of the easing 11. The skirt may be held to the casing 2 by the machine screws 16 or by other suitable means. i

A flange 17 is turned inwardly at the end of the skirt and supports a reflector 18 andan insulating plate 19. Spacing studs, 21, 21

' which may be molded integrally with the central terminal of two lamps 31, 31 maintained in the sockets 32, 32. These may be threaded metal inserts molded into the plate 19.

A metal strip 33 is crimped over a piece of insulating material to form a shoe 84 which may slide in a limited are along the inner wall of the skirt. A laterally extending ham-- dle 35 is threaded into the combined nut and contact element 36 and which moves in the clearance slot 37 cut in the skirt 15.

3. An electric lantern comprising a caslng, a plate of insulating material spaced from the end of the casing, two sockets carried by the plate, lamps in the sockets having their central terminals electrically connected to one pole of a battery in the casing, a skirt extending between the casing and the plate, a shoe of insulating material adapted to slide along the inner wall of the skirt and spring contact members adapted to press outwardly upon the shoe and against the sockets and to engage contacts upon the shoe when the shoe is rotated to an appropriate position.

4. An electric lantern comprising a casing having a permanently closed end, a skirt telescoping over the end of the casing and maintaining an insulating plate spaced therefrom, an insulated terminal in the end of the casing, a battery having its lateral contact electrically connected to the casing and its central contact connected to the insulated terminal, a shoe bearing contacts in electrical connection with the lateral battery contact and adapted to slide along the inner wall of the skirt, a socket in the insulating plate, and spring pressed elements bearing constantly against the shoe and the socket and electrically connecting the battery and the socket when the shoe is in the appropriate position.

'5. In an electric lantern, a casing, a skirt telescoping over the casing and engaging the periphery of'an insulating plate bearing a plurality of spacing studs, a socket in the plate, a slidable insulating shoe having a contact thereon electrically connected to the casing, and a spring member looped about a spacing stud and bearingupon the socket and the shoe to connect the socket to the casing when the shoe is in an appropriate position.

6. In an electric lantern, a casing, a skirt telescopingover the casing and engaging the periphery of an insulating plate bearing a plurality of spacing studs, two sockets in the plate, a slidable insulating shoe having contacts thereon electrically connected to the casing, two spring members looped about the spacing studs each bearing upon a socket and the shoe and which connect the socket to the casing when the shoe is in an appropriate 7 position.

7. In an electric hand lantern, a casing, a plate of insulating material spaced from the casing and bearing a socket, a lamp in the socket, a central battery contact in electrical connection with the base terminal of the lamp, a shoe of insulating material adapted to slide along the inner wall of the casing and having a button projecting through the casing, an electrical conductor extending between the shell contact of the lamp and the out of engagement with the electrical concluctor upon movement of the shoe. In testimony whereof I afiix my signature.
